Description:Kate Middleton is testing out Fall's must-have color trend: burgundy! The Duchess of Cambridge stepped out alongside Prince William at the Middle Temple Treasury, where they launched a program for law students from disadvantaged backgrounds, and Kate styled up a gorgeous bordeaux skirt suit for the occasion. She made this jacket and skirt number by Paule Ka even more Fall-appropriate by styling it with black tights and suede heels. Watch today's Fab Flash for all the details. (0:58)
